cherry blossom is incredibly short lived in my z5 ... a couple days at best ... it was near done blooming when you bought it.. and the transplant finished it off for this season ... in my z5 the flower buds are incredibly sensitive to frost/freeze after winter.. and prior to bloom ... your annual show will vary based on such ... all you should be worried about .... is getting it to live thru summer.. and you should be all set .... where is two face.. TO THE BATCAVE.. lol .. ken

Hi bomber, Not to worry, my stewartia did not flower the first year after it was planted too. The tree is using all its resources to develop a good root system and a balnce with its crown length. Based on the size of the trunk it takes approx a year per inch caliper size for the tree to establish fully You should probably see flowers next year.

Looks like cherry leaf spot, nothing to do with beetles. See how the sick leaves are on the same branch.

being down under.. and it being fall .. and presuming its deciduous ... then i am never really concerned about how the leave look .. this time of year ... they are going to fall off.. and be gone ... in case anything was going on.. clean them all up.. so they wont be there in spring .. just in case ... i would have bought a fall plant with those leaves... ESPECIALLY if it was a fall bargain plant ... if you read that link ... you should know.. fall is one of the prime planting times ... especially on a deciduous tree ... since the various shocks.. will not really hurt leaves that are already primed to fall off ... all the better if they do.. fall is root growing time... and it will have all fall.. winter.. and early spring.. to get those roots settled in.. for the next time the leaves emerge .... NEVER water the leaves of anything.. that is ONLY ma natures job.. otherwise ... you water the roots ... leaves transpire or sweat .. lose water .. though they may take in some minimal water... its not really their job ... and if you water in the evening.. and the leaves go into humid darkness damp .. you could get in trouble with various night pathogens.. the most famous of which is powdery mildews ... since you suspect improper planting... as compared to the link ... and basically just yanked it from the pot ... at a min .. now that it has no leaves.. yank it back out... fluff out at least about half the MEDIA ... cut any severe circling roots ... and replant it in native soil.. per the link ... water it in properly .. and mulch it ... and then.. inserting finger about 2 or 3 inches ... dont water again. until the soil seems to be drying ... which.. in fall. might be weeks or a month from know ... no one can really tell you how it will all work.. in your soil ... and you are responsible for all water next year ... especially in the high heat of summer.. and any droughts ... the year after ... it should be rather self sufficient ... ken
